Procedure

A mixture of 2,6-dichloro-5-fluoro-nicotinonitrile (900 mg, 5.7 mmol), 2,2,2-trifluoro-ethanol (570 mg, 5.7 mmol), and NaH (60%) (273 mg, 6.8 mmol) in N,N-dimethylformamide (15 mL) was heated at 120° C. overnight. The reaction mixture was poured into water, and extracted with ethyl acetate (2×). The solvent was removed to give the title compound (1100 mg, 76%). MS (DCI/NH3) m/z 255 (M)+, 257 (M+2)+.
